<p>I got halfway through running <code>cargo bisect-rustc</code> recently and it gave me this error:</p>
<div class="codehilite"><pre><span></span><code>********************************************************************************
Regression in nightly-2020-11-05
********************************************************************************

fetching https://static.rust-lang.org/dist/2020-11-04/channel-rust-nightly-git-commit-hash.txt
ERROR: Tarball not found at https://static.rust-lang.org/dist/2020-11-04/channel-rust-nightly-git-commit-hash.txt
</code></pre></div>
<p>is there something special about the 4th? or is this a bug in bisect-rustc?</p>

<p>FWIW I figured this out without the commit artifacts, so not a big deal for me if it's a pain to fix</p>
